The Helavia A3x25-FC rubber grommets from Ses-Sterling are specifically designed for use in electrical and installation technology. They serve as protective and guiding elements for cables and wiring, particularly in areas where mechanical or thermal stress is expected. The grommets are available in the colour Red and belong to the product group of protective grommets, which are used in installation technology for the safe and orderly routing of cables through enclosure openings. The designation A3x25-FC refers to the specific version of the grommet, with dimensions and technical properties designed for precise fit in standard installation scenarios.

Rubber grommets are elastic protective elements that shield cables from mechanical damage, such as friction or pressure. The Helavia A3x25-FC is manufactured from an elastic material that offers high flexibility and shape stability. The colour Red serves as a visual identifier and enables easy recognition during the installation process, especially in complex systems with multiple cable bundles. The grommet is designed for a temperature range of -30 to 90 °C, making it suitable for use in indoor and outdoor environments, provided ambient conditions remain within this range.

Functions and equipment in detail

The Helavia A3x25-FC rubber grommets are individual components designed to be directly inserted into drill holes in enclosures, switch boxes, or other electrical devices. They prevent cables from being damaged during routing through openings and simultaneously protect against dust and moisture ingress. The grommet is pulled through by the cable and fits securely in the drill hole, ensuring a safe and tight guide. The elastic structure allows adaptation to different cable diameters within the specified range, with precise fit guaranteed by the specific shape of the grommet.

Technology explained simply

The grommet is made from an elastic polymer that offers high tensile strength and resistance to mechanical stress. The shape of the grommet – with a conical or cylindrical transition – ensures that it elastically deforms when inserted into the drill hole and then returns to its original shape, providing secure retention in the hole. The elastic property allows the cable to be pulled through easily without damage. The grommet is not designed for use in explosive environments or with direct contact with aggressive chemicals, as this is not mentioned in the manufacturer's specifications.

Compatibility and accessories

The Helavia A3x25-FC is designed for use in standard installations, particularly in switch boxes, distribution boxes, and other electrical enclosures that have drill holes of the appropriate diameter. The grommet is not connected to additional components such as screw caps or cable ties, but serves as a standalone protective element. Installation requires no additional tools – the grommet is simply inserted into the hole and the cable is pulled through. Compatibility is limited to drill hole diameters and cable diameters within the specified tolerances.

Installation and mounting

Mounting is done by simply inserting the grommet into the designated drill hole. It is important to ensure that the grommet sits fully within the hole and no edges protrude, which could damage the cable. The cable is then pulled through the grommet, with the elastic structure of the material protecting the cable and simultaneously providing secure anchoring in the hole. Installation requires no special tools or additional effort. The grommet is intended for use in stationary installations, with mechanical stress from the cable and environment remaining within the specified limits.

Advantages in operation

The Helavia A3x25-FC offers a reliable and simple solution for cable routing in electrical installations. The elastic structure protects the cable from mechanical damage and prevents dust or moisture ingress. The colour Red facilitates visual differentiation during installation, especially in systems with multiple cable bundles. The grommet is designed for a temperature range of -30 to 90 °C, enabling broad application in various environments. Simple installation and minimal space requirement make it a practical component in electrical installations.

The packaging contains 100 pieces, enabling economical handling in larger installations. The weight specification of 0.525 g per piece is technically relevant, as it affects transport and storage properties, but is not significant for the user during operation. The product is used exclusively as a single component for cable protection and routing.
